Detailed Description

template<class TYPE>
class Gray::cSingletonStatic< TYPE >

base class for a type that we want to make sure only one of these can exist at a time.

Note

TYPE = cSingletonStatic based class = this Externally created singleton. might be stack based, or abstract (e.g.cNTServiceImpl) but usually static allocated.

Assume 1. gets constructed/destructed by the C Runtime, 2. Is inherently thread safe since its not created on demand. The BIG problem with this is that we cannot guarantee order of creation/destruction. So singletons that rely/construct on each other may be corrupt/uninitialized.

Constructor & Destructor Documentation

cSingletonStatic()

template<class TYPE >

Gray::cSingletonStatic< TYPE >::cSingletonStatic ( TYPE *  pObject )

inlineprotectednoexcept

the singleton must be constructed with a reference to the controlled object typically this == pObject == sm_pThe

~cSingletonStatic()

template<class TYPE >

virtual Gray::cSingletonStatic< TYPE >::~cSingletonStatic ( )

the singleton accessor

This is a complex or abstract or assumed static type that we cannot just create automatically on first usage.

Returns

sm_pThe but allow that it might be nullptr. Weird.
